Multi-Tech Systems MT3410ZLX-T/2 owner manual Basic AT Commands, AT&K3H0Enter

MultiMobile Owner’s Manual

For example, type:

ATH0<Enter> to hang up the modem connection,

or

AT&K3<Enter> to enable bi-directional CTS/RTS hardware flow control.

Most of the AT commands can be entered in “strings” (i.e., on the same command line) without spaces between the individual commands. For example:

AT&K3H0<Enter>

As shown above, it is not necessary to put spaces between the commands. So, there are no spaces between AT, &K3, and H0.

The modem usually returns a response (or “Result Code”) at the next line if it understands the command. The response is usually OK or ERROR unless the AT command provides other (extended) messages.
